I accidentally deleted Google Authenticator for Bittrex and was unable log in to my account. Then I went through several requirements (proof of identity, Recent IP addresses I had used to log into account, Estimated account balance and estimated coin balances) to remove my two-factor authentication and this was all without success and in the end I was exhausted and gave up. But after some time I checked just for fun and I two-factor was removed, and I got my coins back.
Wow, what a great advertisement for Bittrex then, yes? I can imagine now if I lost my account at Poloniex for example, I will just give up. They never replied me before why would they now?
Bittrex has very good customer service and if they actually helped you to recover your lost account like this, I have to say, salutes. Good to hear there are still honest operators in the space.
